Chapter 3
1. In accomplishing a needs analysis in response to a given deficiency, what type of information would you include? Describe the process that you would use in developing the necessary information.

A needs analysis includes a comprehensive assessment of hardware, software, and data needs and identifies future application and staffing requirements. A needs analysis not only looks at the tasks being performed in the system, but also at other parts of the system that might yield clues at what might be done to improve it. Depending upon your goals, you might perform one, both, or a hybrid of the two.

If the deficiency is based on knowledge, a training needs analysis would have to be set up. This can be done in two ways. The first consists of when a training analyst goes into the system or process and searches for problems or potential problems. The goal is to make the system more efficient and to prevent future problems from occurring. When a new employee is needed the required skills, knowledge, and attitudes (SKA) of the candidate are known, and the SKA the candidate must be trained on after being hired are also known.

The second method is when a supervisor or manager comes o the training department for help in fixing a problem. These problems are usually caused by new hires, promotions, transfers, appraisals, rapid expansion, changes, or the introduction of new technologies. Training departments must act rapidly when problems arise that might require a training solution. The lifeblood of the business could depend on it. First, you must investigate the problem. A training need exists when an employee lacks the knowledge or skill to perform an assigned task satisfactorily. It arises when there is a variation between what the employee is expected to do on the job and what the actual job performance is.
When looking for training needs, or when problems arise, there are several instruments that may be used to locate the actual symptoms. Some of these needs ...

Solution Summary

The type of information for a deficiency analysis is provided. The benefits of physical models and mock-ups are provided. The solution is given in an attachment in 1200-1300 words.
